ConclusionFor anyone who has read any of my previous articles you know that I'm not going to mince words. If something sucks I'll tell you it sucks and if it's worth your time I'll preach it from the rooftops. The verdict: Damn Small Linux kicks ass! It just goes to show you that you *can* pack a completely usable, GUI-fied operating system in 50MB. DSL should be part of your toolbox if you routinely rescue dead systems or need to hop from desktop to desktop without reformatting the hard drive.

Damn Small Linux isn't just for older hardware. If you really want that multi-core system to scream, run DSL.
